Technically the load on the threads decreases exponentially as you go down the thread away from the top. however if the load is such that plastic deformation takes place (put too much load on) rather than elastic deformation then the top threads will deform and spread the load further down the thread. In other words, whilst the top threads take the strain, if put to work they then pass the load on to their buddies further up. Team work.

So more thread is best when you may really need it. A toggle thingy would get my vote.
